2009/2010 Calcium Products "Prove It" Promotion

Calcium Products, Inc., (CPI) understands the importance of local yield data when making crop input decisions. To fulfill this need we have designed a program to supply SuperCal SO4 and SuperCal 98G and Trio  for test plots and field trials (plots) to farmers through one of our qualified dealers. This program will offset the cost of SuperCal 98G and SuperCal SO4 for plots. This program will not pay for plot labor, application, equipment, or plot upkeep.

CPI will refund qualified dealers in the form of a product credit.

Qualifications:
Dealer and cooperator will fill out a data sheet on plot test site and submit a plot map. This can be in the form of a plat map or a surety map. Due Date April 1 2010

Dealer must submit soil samples, with full analysis from all plot application sites before application of products. Calcium Products will cover the cost of this test if submitted in our name. Due Date April 1 2010

Tissue Samples will be collected during reproductive stage of growth. Tissue samples will be collected following Midwest Labs guidelines. Calcium Products will cover the cost of this test if submitted in our name. Due Date August 31st 2010

Yield Data may be collected via weigh wagon, or yield map. Due Date Dec 15th 2010

Follow up soil sample will be taken if the plot is 98G. This should be done at the time yield data is collected. Calcium Products will cover the cost of this test if submitted in our name. Due Date Dec. 15th 2009

Corn, Soybeans, Wheat, and Sorghum may be used for this trial.

Data must be submitted by cut off dates to qualify for reimbursement.
Reimbursement will not exceeded 2 tons per customer or trial. Agronomists submitting plots will be limited to 5 trials.

Contact your Calcium Products sales rep for information to submit lab samples.
 
Setting Up the Test
Individual test strips should be as close to each other as possible. This is to insure that differences in crop performance in strips are due to treatment differences and not naturally occurring spatial variation.  In a lime or gypsum vs. untreated side by side comparison one should leave a buffer between the two strips to protect the untreated check strip from variations in application at the outer reaches of the applicator.

• Don't split larger fields, applying half to the field and leaving half the field untreated. Spatial variability can mask real differences. 
• Don't apply to soil too late, applications should be done 1 month prior to planting.

Applying SuperCal

• Select fields that contain a single hybrid or variety.
• Apply a full round in the field rather than a single pass, Apply parallel to rows. 
• Use straight rates, no added potash or phosphates 
• Install replicates of the strips within the same field to increase reliability of the test.
• Use a buffer width of 50 feet (twenty 30-inch rows)
• Clearly mark the application passes using flags or other suitable markers to visually guide the applicator. 
• Permanently identify every treated and untreated strip using GPS or physical markers such as flags or stakes. This will help the combine operator note the exact location of all strips during harvest.

In-Season Monitoring

• Begin monitoring the treated and untreated strips for insects, and diseases at the onset of reproductive stage of the crop. Record any disease or insect problems and severity. Take tissue analysis at this point.
• One week before harvest, note differences in lodging among the strips. Count the number of lodged plants in four row lengths containing 25-consecutive plants for each strip. Total the counts to give percent lodging.

Harvesting the Test

• Harvest all of the end rows and any areas that did not receive a full rate of SuperCal.
• Measure and record the length of the treated and untreated strips with a tape or measuring wheel. 
• Harvest the same number of rows in all strips. 
• Harvest the center of the strip only. Example, if operating an 8 row head only harvest the center 8 rows of the application strip. 
• Use a well-calibrated yield monitor, weigh wagon or elevator scale to determine the grain yields produced in the different test strips. Test a grain sub-sample for moisture content if a weigh wagon or scale is used. 
• Correct yields to 15% moisture for corn, 13% for soybean.
